Have students draw in their x- and y-axes in each section using the bottom of each triangle base as (0,0) (or whatever other point you determine like (0, -5) to have them practice more negative numbers). Starting in section one, students draw something and in each subsequent section, they animate it (using the transformations you have just taught them). When finished, students stick a pencil through the middle and spin it to watch their animation.

For extra practice, divide students into pairs and have them give their partner instructions on how to translate their original image.
